She’s an Araneus species, not A. diadematus. A. trifolium is a possibility, I didn’t check the World Spider Catalog for the common Araneus spp. of Norway. The catalog can’t be completely thorough. Her abdomen is a little shrunken from ovipositing, so she isn’t looking her best.
My best guess is Araneus diadematus.
